Welsh Text-to-Speech Voices
Speech company IVONA created two Welsh text-to-speech voices for Windows PC, Geraint and Gwyneth. You can purchase them from Harpo online:
Make sure you get the Welsh voices, not the English (Welsh-accented) voices also called Gwyneth and Geraint – there are two Gwyneths and two Geraints, and you need the CY Welsh versions your Welsh will not be read correctly.
(You could purchase the voices in 2014 from the RNIB online shop but they have since moved.)
They have been tested with ClaroRead and worked fine for us – although we observed some slight clipping at the end of each sentence, which was confirmed in other non-Claro third-party software.
